01.About Me

I love building all kinds of software. I work solving business problems, and I change the tools and fields I work in according to what the solution needs — from building internal front-end desktop tools at Hogarth Worldwide, to automating end-to-end cloud testing infrastructure at Oracle Cloud Infrastructure, to designing a domain-specific language and editor at SAS Institute. I studied Computer Science at Rice University, where I also served as Vice President of the MMA Club. Outside of full-time work, I've built Consistente, an attendance tracking system for MMA gyms, and Reservao, a booking system similar to Booksy. I'm currently open to new full-time software engineering roles.
